Kernel: 2.6.21.5 OS: Slackware12.0 This is a long time annoying misconception i'm reporting here: When a command is run from a shell and drives the kernel to use 100% of cpu for a while, linux lets printing on screen anything that is typed. This doesn't sound too much annoying at first sight, but actually this confronts the users to a problem: When logging in a shell, one will type his username, 'return' and then his password... But just after 'return' the kernel is launched into thinking for long enough to the point that users who do everything fast including logging in a shell let the shell display the first letters of their passwords. This problem tends to be critical when the user makes a demonstration to a bunch of people thanks to an overhead projector. The time that the kernel takes for checking usernames is about one second on my laptop which is equipped with an intel centrino 1,7GHz. | ||||||||||||
